  [flang] Carry over alignment computed by frontend for COMMON (#94280)

The frontend computes the necessary alignment for COMMON blocks but this
information is never carried over to the code generation and can lead to
segfault for COMMON block that requires a non default alignment.

This patch add an optional attribute on fir.global and carries over the
information.
